K&N 50th

For over 50 years,

K&N® has been an industry-leader in automotive filtration technology—offering best-in-class products for more vehicle applications than any other aftermarket filter manufacturer.   In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N), developed a ground-breaking new idea for an air filter—one that could perform under the demands of dusty, dirty off-road environments.

Five decades later, K&N® is still driving filtration technology forward in the aftermarket, offering protection for everything from top-fuel dragsters to commuter vehicles across the globe.

K&N 50th - Ken and Norm


For the past 50 years, K&N has been re-engineering what filtration can do.
